T. rex Maintained Human-Like Body Temperature, New Research Reveals
New research, based on the analysis of fossil tooth enamel, indicates that the Tyrannosaurus rex maintained a body temperature of approximately 97 degrees Fahrenheit (36 degrees Celsius), similar to that of humans. This finding challenges previous assumptions about the metabolic rates of large carnivorous dinosaurs. Scientists used a technique called clumped isotope thermometry, which measures rare forms of carbon and oxygen in enamel, to determine the temperature at which the mineral formed, reflecting the animal's body temperature. The study, published in the journal Science Advances, analyzed three T. rex teeth from the Hell Creek Formation in Montana, two from an individual named Thomas and one from another animal. The average temperature across these samples was 97.3 degrees Fahrenheit (36.3 degrees Celsius). For comparison, five crocodilian teeth from the same region showed an average temperature of 87.6 degrees Fahrenheit (30.9 degrees Celsius), confirming that the T. rex maintained a significantly ...
